Abstract (en)
[origin: EP0811773A2] The spacer (1) has a spiral cutting profile about a cylindrical centre. This is inserted into a bored hole (7) in the wall panel (5) with the same diameter as the cylindrical centre. The outside end of the insert has a polygonal cross section to provide a grip for a fastening tool. The insert is turned into the wall panel to the required depth. The centre of the cylindrical centre is bored to take a threaded fastener (3) to secure the panel to the wall, with the protruding section of the insert forming the spacer. The cutting edges of the spacer are spiral shaped and with outer cutting teeth. The maximum diameter of the cutting edges has a ratio of up to 3.5 to 1 to the cylindrical centre.
